Description

Handle device for a hand-held power tool

Technical Field

The invention relates to a handle device for detachable fastening at a hand-held power tool, in particular a drilling or screwing machine, wherein the handle device has a clamping ring with a clamping receptacle for receiving a fastening section, in particular a machine neck, of the hand-held power tool, and a handle which projects from the clamping ring and is provided and designed for gripping and/or gripping by an operator, wherein the clamping receptacle can be adjusted by means of a clamping actuating handle which can be manually actuated by the operator between a clamping position in which an inner circumferential surface of the clamping receptacle bears in a clamping fit against the fastening section of the hand-held power tool, and a release position in which the fastening section of the hand-held power tool is released, wherein in the release position the fastening section of the hand-held power tool can be inserted into the clamping receptacle along an insertion axis, and wherein the handle device has an axial form-fitting body which is mounted movably with respect to the clamping receptacle and which has an axial form-fitting contour for engaging into a counter-fitting contour of the fastening section of the hand-held power tool.

Background

Such a handle device is described, for example, in DE 38 29 801 A1. The handle device has a sleeve with a so-called stop lug as an axially form-fitting contour, which engages into a groove at the spindle neck of the hand-held power tool machine by adjusting the clamping receptacle into the clamping position. The clamping receptacle enables a friction-fit, clamping-type retention of the handle device on the hand-held power tool. The axial form-fitting contour serves as an additional form-fitting latching or fixing part in the axial direction with respect to the plug axis. For adjusting the handle arrangement (for example, with regard to the rotational position about the plug-in axis) and/or for disengaging the handle arrangement with respect to the hand-held power tool, the clamping engagement should be disengaged in such a way that the clamping receptacle is adjusted into the disengaged position during an initial rotational actuating phase of the handle. Furthermore, the axial form fit must be eliminated by means of the subsequent rotational actuation phase of the handle.

DE 10 2008 000 516 A1 and WO 2009/109247 A1 describe a hand-held power tool with a spring element which projects as an axial form fit into a clamping receptacle with elastic yield.

Further handle devices are known from DE 10 2006 041 069 A1 or DE 10 2016 207 A1.

In the known handle device, the handling is inconvenient.

Disclosure of Invention

The object of the present invention is therefore to provide an improved handle device.

In order to solve this object, provision is made in a handle device of the type mentioned at the outset for it to have a form-fitting actuating handle which is separate from the clamping actuating handle and can be actuated manually by an operator independently of the clamping actuating handle for adjusting the axial form-fitting body between an engagement position, in which the axial form-fitting contour is in engagement with the counter-axial form-fitting contour and the handle device is form-fittingly locked at the fastening section of the hand-held power tool with respect to the plug-in axis, and a release position, in which the axial form-fitting contour is out of engagement with the counter-axial form-fitting contour and the hand-held power tool and the holding device are displaceable relative to one another with respect to the plug-in axis.

The basic idea here is that the clamping ring can be adjusted between the clamping position and the release position by means of the clamping actuating handle and that the axial form-fit contour can be actuated independently of and/or separately from the clamping actuating handle or the clamping ring by means of the form-fit actuating handle. That is, there are two manipulating handles that can be manually manipulated independently and/or separately from each other.

The axial form-fitting contour is mounted movably and/or can be actuated independently of the clamping ring and/or the clamping receptacle. The axial positive-fit contour is mounted so as to be movable relative to the clamping receptacle.

The axial form-fitting contour is preferably designed as a rib. The mating axial form-fit contour is designed, for example, as a groove, in particular as an annular groove.

A chamfer or lead-in ramp can be provided at the axial form fit contour and/or the mating axial form fit contour, which makes it simple for the axial form fit contour and the mating axial form fit contour to be brought into engagement.

It is advantageously provided that the axial positive-locking contour can be adjusted between the engagement position and the release position by means of a positive-locking actuating handle with the clamping receptacle in the disengaged position and/or with the clamping ring in the disengaged position. It is possible that the clamping between the handle device and the hand-held power tool machine is disengageable, i.e. the clamping ring can be adjusted into its disengaged position, while the axial positive-fit contour remains in engagement with a counterpart axial positive-fit contour of the fixing section of the hand-held power tool machine.

Advantageously, the axial positive-fit contour in the engaged position fixes the handle device at the fixing section in a manner that resists axial displacement and/or positive-fit with respect to the plug-in axis and/or is designed for such fixing. The transverse widths of the axial positive-fit contour and of the mating axial positive-fit contour with respect to the plug axis can thereby be, for example, identical, apart from a movement gap which effects bringing the axial positive-fit contours into engagement with one another. That is to say, the handle device is not displaceable along the plugging axis with respect to the securing section when the axial form-fitting contour engages into the mating axial form-fitting contour.

It is advantageously provided that the axial form-fit contour in the engaged position projects ahead of the inner circumferential surface of the clamping receptacle. The described design of the axial form-fitting contour is advantageous anyway when the clamping receptacle is in the clamping position. It is particularly advantageous, however, if the axial form-fit contour projects in front of the inner circumferential surface of the clamping receptacle in the engaged position when the clamping receptacle is in its disengaged position. The clamping receptacle can thus be disengaged or disengaged, for example, without the axial form fit being eliminated. Thereby, even if the clamping is released, an axial form fit between the handle arrangement and the hand-held power tool can be maintained.

It is advantageously provided that the axial form-fitting contour in the engaged position projects further forward of the inner circumferential surface of the clamping receptacle than in the release position.

It can be provided that the axial form-fit contour in the release position does not project ahead of and/or is aligned with and/or recedes behind the inner circumferential surface of the clamping receptacle. All the previously mentioned embodiments can be realized, for example, in that the adjustment path of the axial positive fit contour between the engagement position and the disengagement position is correspondingly wide. This means that, for example, a plurality of disengagement positions can also be provided. For example, it is possible that the axial positive fit contour, although also in the disengaged position, projects beyond the inner circumferential surface of the clamping receptacle, is no longer in engagement with the mating axial positive fit contour. By means of a corresponding adjustment path of the axial form-fit contour, it can, for example, also be adjusted further away from the inner circumferential surface of the clamping receptacle, so that the axial form-fit contour is aligned with the inner circumferential surface or adjusted back behind it.

Advantageously, the axial positive fit contour in the engaged position projects radially inward before the annular or circular plug-in cross section of the clamping receptacle and in the released position is adjusted back to the plug-in cross section or aligned with the plug-in cross section, so that the clamping receptacle in the released position of the axial positive fit contour provides or releases the circular plug-in cross section for insertion into a fastening section of the hand-held power tool.

The clip accommodating portion has an outer shape such as a columnar shape.

In this connection, it should be mentioned that the plug-in cross section of the clamping receptacle is preferably circular and/or has a diameter of exactly or approximately 43 mm. The handle device is thus compatible with a plurality of hand-held power tools, the fastening section of which has a clamping portion, the outer circumference of which is approximately circular and/or has a diameter of approximately 43 mm. Even if the hand-held power tool does not have a matching mating axial form-fit contour, the axial form-fit contour of the handle device does not cause interference when it occupies its release position or is adjusted into the release position.

Preferably, the clamping ring as a whole and/or in the region of the clamping receptacle is electrically non-conductive or electrically insulating. Advantageously, at least the clamping receptacle is electrically insulating or electrically non-conductive. For example, the clamping receptacle or the clamping ring as a whole is made of a plastic material, in particular a non-conductive plastic material. However, a metallic clamping ring would also be possible without any problem, which directly provides the clamping receptacle. For electrical insulation, the metallic clamping ring can be provided with an electrically insulating coating in the region of the clamping receptacle.

The axial form-fitting body is preferably a separate body from the clamping ring. The axial form-fitting body is preferably a separate body from the clamping ring. The axial form fit is preferably not integral with the clamping ring.

Preferably, the axial form fit body can be adjusted independently of the clamping actuating handle between the engagement position and the release position and/or is not coupled to the clamping actuating handle in a movable manner and/or is not in actuating engagement.

It is preferably provided that the axial form-fitting body can be manipulated between the engagement position and the release position only by means of a form-fitting manipulation handle, in particular from the engagement position into the release position and/or from the release position into the engagement position.

Advantageously, the axial form-fitting body cannot be actuated by a clamping actuating handle. In this way, for example, the clamping actuating handle can be adjusted into a position associated with the clamping position of the clamping receptacle and/or into a position associated with the release position of the clamping receptacle, without the axial form-fitting body being adjusted between the engagement position and the release position in this case.

Advantageously, the axial form-fitting body is adjustable between an engaged position and a released position when the clamping receptacle is in the clamping position. The axial form-fitting body can thereby be adjusted into the release position even when the clamping ring clamps the fastening section of the hand-held power tool.

It is understood that a plurality of axial form-fitting profiles can be provided, that is to say at least two axial form-fitting profiles can be provided. The axial form-fitting profiles can be provided at the same axial form-fitting body. However, it is also possible to provide a plurality of axial form-fitting bodies.

For actuating the at least one axial form-fitting body, a single form-fitting actuating handle can be provided. The form-fitting actuating handle is connected to the axial form-fitting body or the axial form-fitting bodies, for example, by means of a gear mechanism, a driver assembly or the like. However, it is also possible to provide a plurality of form-fitting actuating handles for one axial form-fitting body or for a plurality of axial form-fitting bodies. In this way, the operator can simultaneously actuate the same axial positive-fit body or a plurality of axial positive-fit bodies, for example, by actuating different positive-fit actuating handles, for example, two different positive-fit actuating handles.

Advantageously, the axial form-fitting body and the form-fitting actuating handle are fixedly connected to one another or are one-piece. Alternatively, it is also possible for example for a drive mechanism and/or a transmission mechanism or the like to be arranged between the at least one positive-locking actuating handle and the at least one axial positive-locking body. The entraining mechanism can be or comprise a transmission mechanism, for example. The entraining mechanism can also comprise a passage (Freigang) between the axial form-fitting body and the form-fitting actuating handle.

Although it is possible that the axial form-fitting body can or should be manually manipulated from the engagement position into the release position and vice versa. However, it is preferred that the axial form-fitting body is loaded into the engagement position by a spring assembly. The operator thus actuates the axial form-fitting body in the direction of the release position against the force of the spring assembly, while the spring assembly acts in the opposite direction (that is to say into the engaged position). For example, the axial form-fitting body is designed as a latching unit which is loaded in the direction of the engagement position.

The spring assembly comprises, for example, a coil spring and/or a metal spring. Preferably, the spring assembly is penetrated or penetrated by the clamp anchor for adjusting the clamping ring between the disengaged position and the clamping position.

Advantageously, the spring assembly comprises at least one spring separate from the axial form fit.

The spring assembly is preferably not formed by the elastic articulation of the axial form-fitting body and/or by a spring separate from the axial form-fitting body. The axial form-fitting body therefore has no elastic properties in itself, for example by being articulated in a resiliently movable manner on another body, for example a clamping ring.

It is however obviously possible for the spring assembly to be formed by or to comprise a spring-elastic hinge of an axial form-fitting body, for example, at the base of the clamping ring.

Preferably, the axial form-fitting body is mounted so as to be linearly displaceable along the adjustment axis relative to the clamping ring. The spring or spring assembly acts on the axial form-fitting body, in particular in the direction of the adjustment axis. It is possible that the axial form-fitting body is supported relative to the clamping ring such that it can be displaced only linearly along one or more adjustment axes. Furthermore, it is possible that the axial form-fitting body cannot be twisted or cannot be pivoted relative to the clamping ring. Advantageously, the axial form-fitting body is supported only in a linearly displaceable manner with respect to the clamping ring, but not in a pivotable manner.

Alternatively, however, it would also be possible to carry out the support in a pivotable or displaceable manner between the engagement position and the release position or along a curved path of the axial form-fitting body. For example, the axial form-fitting body is mounted so as to be able to pivot between a release position and an engagement position by means of a pivot bearing or by means of a slide guide along a curved path and/or so as to be able to displace the pivot. The pivot bearing can have, for example, an axis unit connected to the axial form-fitting body, which is mounted on the bearing receptacle so as to be pivotable about a pivot axis.

Preferably, in order to provide a displaceable support of the axial form-fitting body, a guide mechanism or a linear bearing is provided. Preferably, a guide mechanism is provided and/or arranged at the handle and/or the clamping ring for linearly guiding the axial form-fitting body along the adjustment axis. For example, the guide surface of the guide means can be arranged not only at the clamping ring but also at the handle, in particular at a support body of the handle, at which an axial form-fitting body is linearly supported with respect to the adjustment axis.

Preferably, the adjustment axis runs tangentially or at a radial distance tangentially to the inner circumferential surface of the clamping receptacle.

Advantageously, the axial positive fit contour has an inclined or wedge surface for abutting and/or wedging with a counterpart axial positive fit contour, for example the base thereof. The bottom is, for example, a groove bottom designed as a mating axial form-fitting contour of the groove. It is particularly advantageous if the axial form-fit body is designed as a wedge or has a wedge, which is designed and/or provided for wedging with a mating axial form-fit contour of the hand-held power tool machine. Preferably, the inclined or wedge surface is slightly inclined with respect to the adjustment axis. For example, the bevel or wedge surface has a slope with respect to less than 30 °, in particular less than 25 °, preferably even only less than 20 ° or less than 15 °. That is, the bevel or wedge surface and the adjustment axis are angled relative to each other at such an angle. In this connection, it should be mentioned that the chamfer or wedge surface can also have an arcuate profile or an arcuate section. Thus, the bevel or wedge surface need not be a flat or planar surface.

By means of the gradient of the wedge surface or the inclined surface, an adjusting force acting, for example, along the adjustment axis is increased with respect to the pressing force with which the axial form-fitting body acts on the mating axial form-fitting contour. The spring force of the spring assembly, which acts, for example, on the axial positive-fit body, generates a pressing force on the mating axial positive-fit contour, for example, on its base, which is intensified, in particular multiplied, by the aforementioned small angle between the oblique or wedge surface on the one hand and the adjustment axis on the other hand. That is to say that the tangential force introduction of the axial form-fitting body is enhanced as it were.

A preferred concept provides that the handle has a longitudinal central axis, and the adjustment axis is parallel or coaxial to the longitudinal central axis.

An advantageous measure provides that the axial form-fitting contour is supported so as to be displaceable tangentially with respect to the inner circumferential surface of the clamping receptacle and/or with respect to the center of the clamping receptacle.

Preferably, the clamping actuation lever and the positive-locking actuation lever are mounted so as to be movable with different degrees of freedom of movement with respect to the clamping ring, i.e. for example the clamping actuation lever can be rotated with respect to the clamping ring and the positive-locking actuation lever can be displaced with respect to the clamping ring. In this way, embodiments are provided in which the clamping actuation handle is rotatably supported with respect to the clamping ring for adjusting the clamping receptacle between the clamping position and the release position, and in which the form-fitting actuation handle is displaceably supported with respect to the clamping ring for adjusting the axial form-fitting body between the engagement position and the release position. However, it would also basically be conceivable for the positive-locking actuating handle to be rotatably supported with respect to the clamping ring in order to adjust the axial positive-locking contour between the engagement position and the release position. In this case, it is possible for the rotary movement of the positive-locking actuating handle to be converted by means of a transmission into a linear movement of the positive-locking contour.

The axial form-fitting body and the clamping actuator are advantageously arranged coaxially, in particular with respect to a clamping axis which is also explained below and/or with respect to a longitudinal axis of a clamping anchor which is also explained below.

Advantageously, the grip actuation handle is formed by or has a rod-shaped handle body of the handle which can be gripped by the operator on the inside of his hand. In other words, the handle body forms a component part, in particular a significant component part or a main component part, of the handle, which protrudes from the clamping ring and can be gripped and/or gripped by an operator for holding and guiding the hand-held power tool machine.

By exchanging, for example, the handle body or applying a different handle body, the handle can have a different geometric shape, for example having a different diameter and/or being designed with a different length. This enables ergonomic adaptation to be achieved without problems.

Advantageously, a form-fitting actuating handle is arranged between the clamping actuating handle and the clamping ring. In this way, the operator can actuate the positive-locking actuation handle, for example, by grasping the grip actuation handle or the grip body with the thumb and/or forefinger.

An advantageous concept provides that a distance is provided between a grip section of the grip actuating handle (for example the previously mentioned handle body) which is provided for gripping the grip actuating handle and a grip surface of the positive-locking actuating handle which is provided for manual actuation, which corresponds approximately to the distance between a thumb joint in front of the hand of an adult operator and the index finger of this hand when the thumb is extended away from the hand. The operator can thus grip the gripping section of the gripping handle and at the same time engage the handle in the front thumb-joint-manipulation shape. The operator can, for example, axially displace the form-fitting actuating handle toward the gripping section of the clamping actuating handle, in particular for actuating the axial form-fitting body in the direction toward the release position.

At the side facing the positive-locking actuation handle, the handle body, which holds the actuation handle, preferably has a support projection, in particular a flange projection, on which the hand of the operator can be supported, in particular for actuating the positive-locking actuation handle.

Advantageously, the form-fitting actuating handle is designed as an annular or sleeve body. Such a sleeve body has, in particular, a gripping surface provided for manipulation by an operator, which gripping surface runs raised towards its side facing away from the clamping ring and/or has a gripping recess.

The clamping actuating handle is preferably supported independently of the form-fitting actuating handle at the clamping ring.

For manipulation of the clamping ring, clamping the anchor is advantageous. For example, the clamp ring can be adjusted between the clamping position and the disengagement position by clamping the anchor. The clamping anchor can be actuated linearly along the clamping axis by clamping the handle body of the actuating handle, for example by the previously mentioned handle body. The handle body is preferably mounted on the base body of the handle so as to be rotatable about a clamping axis and forms a clamping actuating body. A threaded section is provided at the clamping anchor, for example, which is screwed into a screw receptacle connected in a rotationally fixed manner to the handle body. By rotating the actuating handle body, the clamping anchor can be adjusted linearly relative to the screw receptacle in order to adjust the clamping ring between the clamping position and the release position.

The clamping anchor is preferably exchangeable as already mentioned for the handle body.

It is possible to design the length of the handle differently and/or to achieve a greater or lesser distance between the clamping ring and the clamping actuation handle, in particular the handle body, by means of different lengths of the clamping anchor. For example, distance elements of different lengths, in particular the support bodies mentioned in the detailed description, can be arranged between the clamping actuation handle and the form-fitting actuation handle, in particular such distance elements which are penetrated by the clamping anchor.

The clamping anchor is, for example, a rod-shaped or pin-shaped structural component. The clamping anchor can, for example, tension the opposed ring ends of the clamping ring towards each other for adjustment in the direction towards the clamping position and release them for releasing the clamping (that is to say in the direction towards the release position) for movement away from each other or actively adjust the ring ends away from each other in the direction towards the release position.

That is to say, the clamping anchor extends, for example, between the clamping ring and the clamping actuation handle, in particular the handle body thereof.

Advantageously, the axial form-fitting body is passed through and/or guided at the clamping anchor. In other words, the clamping anchor can simultaneously form a guide element for the axial form-fitting body or the already mentioned guide means.

A preferred embodiment provides that the handle device has at least one rotationally shaped mating contour for engaging into a mating rotationally shaped mating contour at the fastening section of the hand-held power tool machine, wherein the mating rotationally shaped mating contour and the rotationally shaped mating contour, when they are in engagement with one another, fix the handle device in a rotationally fixed manner relative to the fastening section of the hand-held power tool machine about the plug-in axis. The rotary form-fit profile and the counter-rotary form-fit profile can be brought into engagement and out of engagement, for example, by a relative movement of the fixing section and the handle device along the plugging axis. The rotary positive fit profile and the counter-rotary positive fit profile are designed, for example, as rib structures, tooth structures or the like or have such structures. For example, the circular ring-shaped teeth can be provided with a rotationally positive contour and a counter-rotationally positive contour. The rotationally positive fit contour is designed in particular such that the handle device can be fixed in a rotationally fixed manner relative to the fastening section in at least two, preferably a plurality of, angular positions relative to the plug-in axis.

For example, the rotationally form-fitting contour is arranged at an end side of the clamping ring which is penetrated by the plug-in axis. It is particularly advantageous if a rotationally positive fit contour is provided at the mutually opposite end sides of the clamping ring. The handle device can thereby be fixed at the fixing section in an assembly position opposite to each other, wherein the rotating form-fitting profiles engage into each other. The handle projects from a fixed section of the hand-held power tool at the respective other side opposite to each other in the two mounting positions.

Advantageously, the axial form-fit contour in the engaged position fixes the handle device at the fixing section in a manner that it is axially displaceable and/or form-fit in relation to the plug-in axis such that the rotary form-fit contour is held in engagement with the counter-rotary form-fit contour and/or is designed for such a fixing. For example, the distance of the axial form fit contour from the rotational form fit contour or to the rotational form fit contour at the mutually opposite end sides of the clamping ring is dimensioned such that the axial form fit contour in the engaged position fixes the handle device at the fixing section in a manner that it is axially displaceable with respect to the plug-in axis and/or form-fittingly such that the rotational form fit contour is held in engagement with the counterpart rotational form fit contour when the handle device is fitted at the fixing section.

An advantageous concept provides that the axial form-fitting contour, in its engaged position engaging into the mating axial form-fitting contour or in an intermediate position between the engaged position and the disengaged position, holds the handle device at the fixing section in an axially displaceable, yet loss-proof manner with respect to the plug-in axis by a predetermined adjustment path. For example, it is possible that the axial positive fit contour in the engaged position holds the handle device at the fastening section in a rotationally fixed manner with respect to the plug-in axis and in the disengaged position enables removal of the handle device from the fastening section, while in the intermediate position a part of the axial positive fit contour or a partial section thereof engages into the mating axial positive fit contour, while allowing axial play of the handle device with respect to the plug-in axis relative to the fastening section of the hand-held power tool machine.

For example, the transverse width of the mating axial positive-fit contour with respect to the plug axis can be dimensioned and/or an adjustment path can be provided such that the axial positive-fit contour, although engaging into the mating axial positive-fit contour, is nevertheless accommodated movably therein along the plug axis in the engaged position or in the intermediate position mentioned above. It is also possible for this axial mobility or adjustment path to be realized, for example, by an inclined profile of the axial positive-fit profile, which runs obliquely with respect to a free end region or a front region of the axial positive-fit profile, and/or by a retaining projection of the axial positive-fit profile, which projects in front of a base body of the axial positive-fit profile or the like.

Preferably, the axial adjustment path in the engagement position or in particular in the aforementioned intermediate position is dimensioned such that the rotary positive-fit contour of the handle device and the mating rotary positive-fit contour of the securing section can be brought out of engagement and into engagement with each other. Thus, the axial form-fitting contour, although engaging into the mating axial form-fitting contour, is retained in the fastening section in a manner that prevents the handle device from being lost. However, the handle device can be moved along the plugging axis away from the counter-rotating form-fitting contour, so that it can be rotated about the plugging axis.

Preferably, the hand-held power tool machine is a drilling machine or a screwing machine. The hand-held power tool advantageously forms part of a system comprising the hand-held power tool and a handle device. Preferably, the working tool which can be mounted on the hand-held power tool is a drilling tool or a screwing tool.

Detailed Description

The system 5 comprises a hand-held power tool 10, for example a screwing tool, and a handle device 30.

The machine housing 11 of the hand-held power tool machine 10 has a drive section 12 from which a handle section 13 projects. An energy store 14A, for example, a battery pack, is detachably arranged at the free foot section 14 of the handle section 13 facing away from the drive section 12 for supplying the hand-held power tool 10 with electrical energy. Alternatively to the mobile energy store 14A or in addition thereto, the hand-held power tool machine 10 also has a network connection, in particular a network cable, for connection to an electrical energy supply network.

In the drive section 12, a drive motor 15, for example an electric or pneumatic drive motor, is arranged, which has a tool receptacle 17 for arranging a working tool 19, for example a screwing tool or a drilling tool, directly or via a transmission 16. The drive motor 12 drives the tool holder 17, for example, about the axis of rotation DA.

The drive motor 15 can be switched on and off by means of the switch 18, in particular also in terms of its rotational speed.

The tool receiver 17 is arranged on a fastening section 20 of the hand-held power tool machine 10, for example a so-called machine neck.

Items, such as a drill floor and in particular a handle device 40 explained below, can be plugged in along a plugging axis S to the fastening section 20.

The fastening section 20 has a receiving section 21, which extends between a free end face 22 of the fastening section 20, at which the tool receiver 17 is arranged, and an end face 23 of the machine housing 11 (in particular of the drive section 12). The receiving section 21 has a cylindrical outer shape with respect to the plug axis S. The receiving section 21 has a retaining surface 24, which is designed as a cylinder circumference or a cylinder circumference extending around the plug axis S with respect to the plug axis S. The holding surface 24 is suitable as a clamping surface. The end side 23 is angled, for example at right angles, with respect to the holding surface 24.

In order to positively fix the object parallel to the plug axis S at the fastening section 21, a mating axial positive-fit contour 22 is provided at the retaining surface 24. A mating axial form-fitting contour 25 is provided between the end sides 22 and 23 at the receiving section 21. The mating axial form-fitting contour 25 is designed, for example, as a groove 26 having a base 27, from which a side wall or support surface 28 extends as far as the retaining surface 24, for example, at right angles.

Preferably, the mating axial form-fit contour 25 extends around the entire outer circumference of the receiving section 21 with respect to the plugging axis S. However, it would also be possible for the mating axial form-fitting contour to extend only over a partial circumference of the receiving section 21. Advantageously, a plurality of mating axial form-fitting contours can also be provided, which are arranged at the receiving section 21, for example adjacent to one another with respect to the plug-in axis S and/or adjacent to one another in the circumferential direction with respect to the plug-in axis S. The mating axial form-fitting profiles arranged adjacent to one another with respect to the plugging axis S can be designed, for example, in the type of a rib structure comprising two or more receiving grooves. The mating axial positive-fit contours arranged adjacent to one another in the circumferential direction with respect to the plug axis S at the receiving section 21 can, for example, each extend in an angular section around the plug axis S, for example, be designed as a partial annular receiving groove.

The rotary positive fit contour 30 serves to positively hold the items at the fastening section 20 in the circumferential direction or the direction of rotation about the plug-in axis S. The rotationally positive fit contour 30 projects, for example, before the end face 23 up to the retaining face 24 and/or radially outward before the retaining face 24. The rotary positive-fit contour 30 has, for example, a plurality of positive-fit projections 31 which project parallel to the plug axis S in front of the end face 23. The rotary positive fit profiles 30 have the same radial spacing 32 with respect to the plug axis S, so that an object to be fixed at the fixing section 20 can be fixed in a plurality of angular positions, the angular spacing of which corresponds to the spacing 32.

The fastening section 20 is arranged on a fastening body 35 of the hand-held power tool 10, which forms part of the machine housing 11 or is connected thereto. The fixing body 35 comprises a peripheral wall 36, the radial outer periphery of which provides the retaining surface 24, and an end wall 37 which projects in flange-like fashion in front of the peripheral wall 36, at which the end face 23 is provided.

An attachment 17A, such as a drill chuck, an angle attachment (winkelvisatz) or the like, can also be arranged on the tool holder 17. A working tool 19A (e.g. a drill) can be releasably fixed at the attachment 17A (exemplarily a drill chuck according to fig. 2). It is precisely for the drilling operation that the operator can safely grip the hand-held power tool in order to maintain the forces occurring during the drilling operation. For this purpose, the hand-held power tool can be gripped not only at its machine housing 11, for example at the handle section 13 and, if appropriate, also at the drive section 12, but also by means of a handle device 40 which can be detachably connected to the hand-held power tool 10.

The handle device 40 has a clamping ring 41 for fastening to the hand-held power tool 10. The clamping ring 41 comprises a clamping receptacle 42, into which the fastening section 20 of the hand-held power tool 10 can be inserted along the plug-in axis S. The clamping receptacle 42 has a cylindrical inner circumferential surface 43, in particular a clamping surface, which is provided and designed for clamping with the holding surface 24 of the hand-held power tool 10. When the clamping receptacle 42 rests with a clamping fit against the holding surface 24, the handle arrangement 40 is held with a friction fit on the hand-held power tool 10.

The clip ring 41 has an annular body 44 that bounds the clip accommodating portion 42. The annular body 44 has a peripheral-side slot 45A, by means of which the insertion cross section of the clamping receptacle 42 can be adjusted about the insertion axis S. The slot 45A runs radially with respect to the plug axis S. The loop ends 45 and 46 of the annular body 44 lie opposite one another in the region of the slot 45A. The plug-in cross section of the clamping receptacle 42 can be reduced with respect to the plug-in axis S by actuating the ring ends 45 and 46 of the clamping ring 41 toward one another along the clamping axis SP in order to clamp the fastening section 20 of the hand-held power tool in the clamping position K that can be formed thereby. The clamping position K is shown in dashed lines in fig. 7. When the ring ends 45 and 46 are moved away from each other, the plug-in cross section of the clamping receptacle 42 is enlarged and is adjusted into a disengagement position L, which is shown in solid lines in fig. 7 and in which the securing section 20 can be displaced in the clamping receptacle 42 about the plug-in axis S.

The rotary positive fit contour 50 provided at the mutually opposite end sides 47 and 48 of the clamping ring 41 for engaging the rotary positive fit contour 30 of the hand-held power tool 10 ensures that the clamping ring 41 is held in a rotationally fixed manner at the fastening section 20 about the plug-in axis S. By providing a rotary form-fit contour 50 at each end side 47 and 48 of the clamping ring 41, the rotary form-fit contour 30 of the fastening section 20 can be brought into engagement with the rotary form-fit contour 50 of the handle device 40 in each plugging direction with respect to the plugging axis S.

The rotary positive-fit contour 50 comprises a positive-fit receptacle 51 for engaging the positive-fit projection 31, which has an angular spacing 52 with respect to the plug axis S, which corresponds to the spacing 32. Advantageously, the positive-fit receptacles 51 have an angular width in the region of the ring ends 45 and 46 of the clamping ring 41 with respect to the plug-in axis S, in order to achieve a movement play of the clamping ring 41 in the region of the ring ends 45 and 46 with respect to the rotating positive-fit contour 30 when adjusting from the disengaged position L into the clamping position K.

The handle 60 extends from the grip ring 41. The handle 60 has a support body 61 which is supported at the clamping ring 41. The support body 61 comprises a sleeve body 62, in front of which a support projection 63 projects. The support projection 63 projects to the receptacle 53 at the ring end 46 of the annular body 44. The support contour 64 of the support body 61 is supported about the clamping axis SP at the support contour 54 of the clamping ring 41. The support contour 54 is formed, for example, on the end side of the peripheral wall 55 of the receptacle 53, but can also comprise a step in the interior of the receptacle 53 without problems.

The clamping anchor 66 serves for adjusting the clamping ring 41 between the clamping position K and the release position L, which clamping anchor penetrates the clamping ring 41 in the region of the ring ends 45 and 46 in order to move the ring ends 45 and 46 toward one another for adjusting the clamping receiver into the clamping position K or to allow or urge the ring ends 45 and 46 away from one another for adjusting in the direction of the release position L. The clamping anchor 66 has a head 67, which is received in the receptacle 49 in a rotationally fixed manner at the loop end 45 and is arranged at the pin section 68. The head 67 and the receptacle 49 have, for example, mutually complementary, in particular polygonal, anti-rotation contours.

The pin section 68 passes through the through openings 56 and 57 at the ring ends 45 and 46 and the support body 61 and engages with the free ring end into an insertion opening 77 of the handle body 70 of the handle 60. At the free end of the pin section 68, a thread is provided which is screwed into a nut 69, which is received in the handle body 70 in a rotationally fixed manner.

Furthermore, it is advantageous to arrange a stop 69A, for example a rotationally fixed nut, a flange projection or the like, at the free end of the pin section 68, which limits the adjustment path of the nut 69 along the pin section 68, so that the nut 69 can not be lost and/or the pin section 68 cannot be completely unscrewed from the nut 69. Thus, that is, the stop 69A forms a loss prevention member for the nut 69.

The handle 60 and in particular the handle body 70 have a longitudinal profile and extend along a longitudinal mid-axis LM of the handle 60.

The handle body 70 is rotatable relative to the support body 61 and relative to the annular body about a rotational axis D, which is preferably coaxial to the clamping axis SP and/or coaxial to the longitudinal central axis LM, whereby the nut 69 is screwed along the pin section 68 and thereby moves the head 67 of the clamping anchor 66 forming the support body towards or away from the handle body 70. The ring end 45 is thereby actuated into the clamping position K toward the ring end 46 or actuated or released for movement away from the ring end 46 in the direction toward the release position. The hand H of the operator BE can rotate the operating handle body 70 and thus the operating nut 69 about the axis of rotation D, for example, in such a way that a plurality of fingers F grip the gripping section 71. The handle body 70 forms a grip actuation handle 78 for adjusting the grip receptacle 42 between the disengaged position L and the grip position K.

It is clear that, instead of the nut 69, a thread can also be provided directly or integrally at the handle body 70 for screwing in the pin section 68. Furthermore, the handle body 70 can also have a screw projection which is screwed into a screw receptacle at the ring end 45 of the ring body 44 in order to facilitate a clamping operation about the clamping axis SP.

The handle body 70 has a grip section 71 for gripping by an operator. The gripping section 71 extends between support projections 72 and 73 at the free end region of the handle 60 or facing the support body 61. The support tabs 72 and 73 are designed in the type of flange tabs. The handle body 70 furthermore has a holding receptacle 74 for the nut 69.

An elastic layer 75 is preferably provided in the area of the gripping section 71 and/or the support tab 72.

At the support projection 73, a reinforcement 76 is advantageously provided, by means of which the handle body 70 is supported at the support body 61.

The axial form-fitting body 80, which has an axial form-fitting contour 81 for engaging into a mating axial form-fitting contour 25 of the fastening section 20, serves to positively lock or fasten the handle arrangement 40 axially with respect to the plug-in axis S at the fastening section 20 of the hand-held power tool machine 10. The axial form-fitting contour 81 has a front face 82 which lies opposite the bottom 27 of the groove 26 or is supported at the bottom 27 with the axial form-fitting contour 81 in engagement with the counter-axial form-fitting contour 25. From the front face 82, a support face 83, for example a side face or a side wall, extends at an angle away (for example at right angles) and is provided for form-fitting support at the support face 28 of the groove 26.

The axial form-fitting body 80 is displaceably supported along the adjustment axis SA by means of a guide mechanism 87 between an engagement position E, in which the axial form-fitting profile 81 is in engagement with the counter-axial form-fitting profile 25 or the groove 26, and a disengagement position L, in which the axial form-fitting body 80 or the axial form-fitting profile 81 is disengaged from the counter-axial form-fitting profile 25.

The front face 82 is inclined obliquely with respect to the adjustment axis SA and forms a bevel 82B or has a bevel as a lead-in ramp 82B. The introduction of the ramp 82B makes it easy to bring the axial form-fitting profile 81 into engagement with the counter-axial form-fitting profile 25.

A clamping anchor 87, which penetrates the through-opening 86 of the axial form-fitting body 80, can be used, for example, as a component of the guide means 87. The axial form-fitting body 80 is mounted displaceably along the clamping anchor 87 about the adjustment axis SA.

Furthermore, the receptacle 53 at the clamping ring 41 is designed to receive and/or guide the axial form-fitting body 80. The axial form-fitting body 80 is accommodated in the receptacle 53 and/or guided along the adjustment axis SA.

The substantially cylindrical section 88 of the axial form-fitting body 80 is received, for example, in the substantially cylindrical guide receptacle 58 at the ring end 46.

In the release position F, the axial form-fitting body 80 is merely in the guide receptacle 58 and/or is retracted into the guide receptacle 58. In the engagement position E, the axial form-fitting body 80 projects in front of the guide receptacle 58 and it sinks into the support receptacle 59 at the ring end 47, which is opposite the guide receptacle 58 and is aligned therewith. However, it would basically also be possible for the axial form-fitting body 80 to engage at least partially into the support receptacle 59 in the release position F even in the case of corresponding lengths. Preferably, the support receptacle 59 and the guide receptacle 58 have the same cross section transversely to the adjustment axis SA. In the engaged position E, the axial form-fitting body 80 is thereby supported transversely to the plug-in axis S at the two ring ends 46 and 47 and the handle device 40 can thereby be optimally supported at the fastening section 20 of the hand-held power tool machine 10 with respect to forces acting axially in the direction of the plug-in axis S.

Furthermore, the axial form-fitting body 80 is preferably guided in a rotationally fixed manner about the adjustment axis SA at the handle device 40, for example about the clamping ring 41. For this purpose, the axial form-fitting body 80 has, for example, a rotation prevention contour 89, in particular a guide projection projecting radially outward with respect to the plug axis S, which is in engagement with a counter rotation prevention contour 59A, for example a groove, a slot or similar other guide receptacle. The anti-twist profile 89 and the counterpart anti-twist profile 59A extend parallel to the adjustment axis SA and preferably have a longitudinal profile with respect to said adjustment axis.

The form-fitting actuating handle 90 serves to actuate the axial form-fitting body 80. Although the positive-locking actuating handle 90 can in principle be coupled to the axial positive-locking body 80 in a movable manner, for example by means of entraining contours engaging in one another, it is preferably integral with the axial positive-locking body 80.

The positive-locking actuating handle 90 comprises a gripping section 91, designed as a sleeve body 91A, which is arranged at an end region of the section 88 of the axial positive-locking body 80 facing away from the axial positive-locking contour 81. The gripping section 91 has a gripping surface 92, which preferably has an inclined profile and/or a gripping recess. The gripping surface 92 is elevated from the grip ring 41 in a direction toward the handle body 70. The grip surface 92 can thus BE grasped conveniently by the thumb DA of the operator BE and manipulated along the adjustment axis SA in a direction toward the handle body 60 when the operator BE grips the handle body 60 with its other fingers F.

At its side facing the clamping ring 41, the form-fitting actuating handle 90 has a receptacle 93 into which the peripheral wall 55 engages, which bounds the receptacle 53 at the clamping ring 41. The parts engaging into each other can also form an integral part of the guide means 87. In any case, the peripheral wall 55 engages in the engagement position E into the receptacle 93 of the gripping section 91. Advantageously, the peripheral wall 55 also engages at least partially into the receptacle 93 in the release position F.

The axial form-fitting body 80 and thus the axial form-fitting contour 81 are spring-loaded into the engagement position E by means of a spring assembly 95. The spring assembly 95 includes a spring 96, such as a coil spring. The spring assembly 95 is supported on the one hand in the receptacle 94 at the axial form-fitting body 80, for example at a longitudinal end region of the section 88 facing the handle body 70; on the other hand, at the support body 61, for example at its support projection 63, in particular at the end side of the support projection 63. That is, the axial form fit is manipulated from the engagement position E into the release position F against the force of the spring assembly 85. The release position F is associated with a stop 65 which is fixed in position with respect to the handle 60. The stop 65 is formed by or provided by a support contour 64 of the support body 61, for example, at which the stop 97 of the gripping section 91 stops in the release position F.

In order to be able to easily bring the axial form-fitting contour 81 into engagement with the groove 26, a chamfer 84 is provided at the front face 82, which is raised toward a free end 85 of the axial form-fitting body 80, such that the free end 85 has a greater distance to the clamping receptacle 42 or the inner circumferential surface 43 than the region of the front face 82 facing the section 88 of the axial form-fitting body 80.

Advantageously, a rounded region 82A is provided at the front face 82, the rounding of which approximately corresponds to the rounding of the inner circumferential face 43, so that in the engagement position E the region 82A can bear in a form-fitting manner against the base 27 of the groove 26.

At the front face 82, a bevel or wedge face 82B is furthermore formed, which can be brought into engagement therewith in the sense of wedging with the mating axial positive-fit contour 25. The wedge surface 82B is inclined at an angle α relative to the adjustment axis SP. The angle α is an acute angle of, for example, approximately 5 ° to 25 °, in the present case approximately 10 ° to 15 °. By means of the wedge surface 82B, an adjusting force Fs acting along the adjustment axis SP, for example generated by the spring assembly 95, is converted into a pressing force Fa, which acts on the bottom 27 of the mating axial positive-fit contour 25. The slight slope of the wedge surface 82B, i.e. the small angle α, therefore causes the force to increase, i.e. the pressing force Fa is greater, in particular several times greater, than the adjustment force Fs.

Advantageously, the handle device 40 has a depth stop element 99 for setting the penetration depth of the working tool 19 or 19A into the workpiece. The depth stop element 99 is, for example, a rod which is displaceably accommodated parallel to the plug axis S in the receptacle 98 of the handle device 40. The receptacle 98 is provided at the clamping ring 41, in particular at the ring end 45.

When the handle arrangement 40 is to be removed from the hand-held power tool 10, it is provided that the clamping receiver 42 is first adjusted from the clamping position K into the release position L. For this purpose, it is sufficient to twist the handle body 70 slightly (that is, to hold the operating knob 78) about the rotation axis D. The operator then disengages the positive locking by adjusting the axial positive-fit body 80 from the engagement position E into the release position F in such a way that it adjusts the positive-fit actuation handle 90 in a direction towards the handle body 70, for example by displacing the front thumb joint DAG of his thumb DA. For this, a short adjustment path is sufficient. The operator can then, for example, completely remove the handle arrangement 40 from the fastening section 20 of the hand-held power tool machine 10, i.e. along the plug-in axis S.

It is also possible for the operator to adjust the handle arrangement 40 only partially along the plug-in axis S, so that the positive- fit contours 30, 50 are rotated out of engagement and the handle arrangement 40 can be twisted about the plug-in axis S about the hand-held power tool 10. If a suitable angular position of the handle arrangement 40 relative to the machine housing 11 is set, the handle arrangement 40 is adjusted again in the direction of the plug-in axis S toward the machine housing 11, wherein the rotary positive fit profiles 30, 50 come into engagement with one another. Advantageously, the axial form-fit body 80 is also snapped into the mating axial form-fit contour 25 by force loading of the spring assembly 95.

The concept illustrated in fig. 9 provides that the axial form-fitting body 80 is merely provided as a safety measure in addition to the clamping of the handle arrangement 40 at the hand-held power tool 10, which merely prevents the complete removal of the handle arrangement 40 from the hand-held power tool 10. In fig. 9, the elements described up to now are structurally identical, in particular the handle arrangement 40 is not modified, but an alternative fixing body 35A or an alternative hand-held power tool 10A equipped therewith is provided. Instead of the counter axial form-fitting contour 25, a counter axial form-fitting contour 25A which is wider with respect to the plug-in axis S is provided with a wider groove 26A, whose support face 28A has a greater spacing with respect to the plug-in axis S than the support face 28. As a result, the handle arrangement 40 can be displaced along the retaining surface 24 along the plug-in axis S after the clamping of the clamping receptacle 42 has been released (i.e. after it has been adjusted into the release position L), but only so far that the axial form-fitting body 80 comes into form-fitting abutment against one of the support surfaces 28A. The width of the groove 26A or of the mating axial form-fitting contour 25A relative to the plug-in axis S is dimensioned such that the rotary form-fitting contour 30, 50 can be brought out of engagement and into engagement by an axial displacement of the handle arrangement 40 and the hand-held power tool machine 10A relative to one another along the plug-in axis S in the adjustment path VS, whereas the handle arrangement 40 can be removed from the hand-held power tool machine 10A when the axial form-fitting body 80 is adjusted into a release position F in which it no longer engages into the mating axial form-fitting contour 25A. It is understood that alternatively or in addition to the solution described, it is also possible, for example, to vary the width of the axial form-fitting profile 81 with respect to the plugging axis S, so that the axial form-fitting body 80 in the engagement position E also has a play with respect to the plugging axis S, for example also in the groove 26 or the mating axial form-fitting profile 25, which play enables bringing the rotating form-fitting profiles 30, 50 into or out of engagement.

In the case of the axial form-fitting body 80A shown in fig. 4, it can be said that the two solutions explained up to now are combined with one another, namely, on the one hand, the axial form-fitting body 80A in the engagement position E at least with a support surface 83, which has a greater distance to the counter-rotating form-fitting contour 30 in the corresponding counter-fitting of the handle arrangement 40 at the hand-held power tool 10, abutting against the support surface 28 of the groove 26 that is the farthest away from the counter-rotating form-fitting contour 30, and thus achieving a form-fitting retention of the handle arrangement 40 at the hand-held power tool 10 not only in the radial direction of the plug-in axis S but also in the axial direction with respect to the plug-in axis S, even when the clamping ring 41 is adjusted into the disengagement position L. Furthermore, the axial form-fitting body 80A can also be adjusted by means of the form-fitting actuating knob 90 into a release position F, in which it no longer engages into the mating axial form-fitting contour 25, so that the handle arrangement 40 can be completely removed from the hand-held power tool.

Furthermore, an intermediate position Z of the axial form-fitting body 80 can be set between the engagement position E and the release position F, in which, for example, the retaining contour 81A projecting before the chamfer 84 is still in engagement with the counter-axial form-fitting contour 25. The retaining contour 81A is designed, for example, as a retaining projection, in particular as a rib, a chamfer or the like, which projects in front of the front face 82, however with a spacing from the support face 83 with respect to the plug axis. When the axial form-fitting body 80A is adjusted into the intermediate position Z, the handle arrangement 40 has a play of movement about the plug-in axis S such that the support surface 83A or the retaining profile 81A of the retaining projection can be displaced about the plug-in axis S between the support surfaces 28 of the grooves 26, so that the rotating form-fitting profiles 30 and 50 can be brought out of engagement and into engagement, however, the handle arrangement 40 cannot be removed from the fastening section 20 of the hand-held power tool machine 10.
